 ## [Unreleased]
 
+### Fixed
+- Kaguya IsisLabelIsisSpice now calculates the right exposure_duration and focal2pixel_lines [#487](https://github.com/DOI-USGS/ale/pull/487)
+- Logging from generate_isd now correctly limits logging information [#487](https://github.com/DOI-USGS/ale/pull/487)
+
+### Changed
+- Projection information is only written to the ISD if a projection is present instead of writing an empty projection [#528](https://github.com/DOI-USGS/ale/pull/528/)
+
+### Added
+- Projection information (through GDAL) will be attached to the ISD if a projected product is processed through ALE [#524](https://github.com/DOI-USGS/ale/pull/524)
+- Kaguya IsisLabelNaifSpice driver, tests, and test data [#487](https://github.com/DOI-USGS/ale/pull/487)
+- Hayabusa Amica IsisLabelNaifSpice driver, tests and test data [#521](https://github.com/DOI-USGS/ale/pull/521)
